Discussion on the Problems and Countermeasures of Using Thermal Conductive Pads in Avionics Products
The importance of heat dissipation in avionics products and the characteristics of thermal pads are intro-duced.The problems that the thermal pad hardness and dimensional to tolerances,printed board deformation and un-reasonable structural design that exist when thermal pads are used in the assembly process of avionics products,as well as poor assembly accuracy of the whole machine and other problems and their causes,are analyzed.Then solutions are proposed such as reducing initial assembly stress,strengthening assembly design,and controlling tolerances in order to provide reference for subsequent design selection and assembly of thermal pads.
